PURPOSE:To eliminate the overhead of recovery by defining the word blocks which store the control information needed for the control of the data transfer for each logic channel. CONSTITUTION:An interpolation memory means 201 stores the control information on the data transfer carried out via the logic channels. The areas corresponding to those logic channels are provided to the means 201. A channel controller 2 outputs the signal showing the allocation state of the means 201 against the logic channels to a central processing unit 1. Then the input/output request transmission circuit 101 of the unit 1 decides the propriety for the generation of an input/output request based on said signal received by the unit 1. |
